An error code displays on the remote controller.
The LED on the Lossnay circuit board is blinking or lit up.
An error code displayed on the remote controller ( PZ-60DR-E ) or the M-NET controller, and blinking or illumina-
tion of LED1 ( green ) or LED2 ( red ) on the circuit board shows the type of an error. The LED blink interval is
0.25 seconds for both on and off. The display duration is approximately 5 seconds.

Action
Turn off the main power supply and
set the Main/Sub selection switch
( SW1 ) ( first unit to " Main " , second
and following units to " Sub ") .
Use suitable cables to wire the
transmission cables so that they
are separated from one another.
Wire the transmission cable at least 2 in. (5
cm) away from the power supply cable.
Check the transmission cable con-
nection.
Check the length of the transmis-
sion cable wiring.
